This book describes isolated actinobacteria from different environments, and how these can be used to bioremediate heavy metals and pesticides in contaminated sites. It also describes how free-living actinobacteria acquire the capability to produce nodules in plants and how this factor could be important for accelerating the degradation of pesticides in soils or slurries. Some chapters show how actinobacteria can be used to produce industrial enzymes and metabolites under different physicochemical conditions for use in the food industry. This book will interest professionals involved with waste management, environmental protection, and pollution abatement.
This book provides an up-to-date overview of the architecture and biosynthesis of bacterial and archaeal cell walls, highlighting the evolution-based similarities in, but also the intriguing differences between the cell walls of Gram-negative bacteria, the Firmicutes and Actinobacteria, and the Archaea. The recent major advances in this field, which have brought to light many new structural and functional details, are presented and discussed. Over the past five years, a number of novel systems, e.g. for lipid, porin and lipopolysaccharide biosynthesis have been described. In addition, new structural achievements with periplasmic chaperones have been made, all of which have revealed amazing details on how bacterial cell walls are synthesized. These findings provide an essential basis for future research, e.g. the development of new antibiotics. The book’s content is the logical continuation of Volume 84 of SCBI (on Prokaryotic Cytoskeletons), and sets the stage for upcoming volumes on Protein Complexes.
This is an insiders account of 50 years of genetic studies of the soil-inhabiting microbes that produce most of the antibiotics used to treat infections, as well as anti-cancer, anti-parasitic and immunosuppressant drugs. The book begins by describing how these microbes the actinomycetes were discovered in the latter part of the nineteenth century, but remained a Cinderella group until, in the 1940s, they shot to prominence with the discovery of streptomycin, the first effective treatment for tuberculosis and only the second antibiotic, after penicillin, to become a medical marvel. There followed a massive effort over several decades to find further treatments for infectious diseases and cancer, tempered by the rise of antibiotic resistance consequent on antibiotic misuse and over-use. The book goes on to describe the discovery of gene exchange in the actinomycetes in the context of the rise of microbial genetics in the mid-20th century, leading to determination of the complete DNA sequence of a model member of the group at the turn of the millennium. There follow chapters in which the intricate molecular machinery that adapts the organisms metabolism and development to life in the soil, including antibiotic production, is illuminated by the DNA blueprint. Then come an up-to-the minute account of the use of genetic engineering to make novel, hybrid, antibiotics, and a topical description of techniques to learn the roles of the thousands of genes in a genome sequence, throwing a powerful light on the biology of the organisms and their harnessing for increasing antibiotic productivity. In the final chapter we return to the mycobacteria that cause tuberculosis and leprosy, the first actinomycetes to be discovered, and how methodology, in part derived from the study of the streptomycetes, is being applied to understand and control these still deadly pathogens.
The first contribution summarizes current trends in research on medicinal plants in Mexico with emphasis on work carried out at the authors' laboratories. The most relevant phytochemical and pharmacological profiles of a selected group of plants used widely for treating major national health problems are described. The second contribution provides a detailed survey of the so far reported literature data on the capacities of selected oxyprenylated phenylpropanoids and polyketides to trigger receptors, enzymes, and other types of cellular factors for which they exhibit a high degree of affinity and therefore evoke specifice responses. And the third contribution discusses aspects of endophytic actinobacterial biology and chemistry, including biosynthesis and total synthesis of secondary metabolites produced in culture. It also presents perspectives fo the future of microbial biodiscovery, with emphasis on the seondary metabolism of endophytic actinobacteria.
The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea
This book presents a detailed discussion on the direct interactions of plants and microorganisms in the rhizosphere environment.
